       struct udev_enumerate *udev_enumerate_new(struct udev *udev);

       struct udev_enumerate
                                                 *udev_enumerate_ref(struct udev_enumerate *udev_enumerate);

       struct udev_enumerate
                                                   *udev_enumerate_unref(struct udev_enumerate *udev_enumerate);

RETURN VALUE         top

       On success, udev_enumerate_new() returns a pointer to the

       udev_enumerate_ref() returns the argument that it was passed,
       unmodified.  udev_enumerate_unref() always returns NULL.

HISTORY         top

       udev_enumerate_new(), udev_enumerate_ref(), and
       udev_enumerate_unref() were added in version 221.
